Abstract
THIS star, which appeared as a so-called nova in 1866 and then faded to magnitude 9, was observed by Mr. N. F. H. Knight on Feb. 9d. 5h. 30m. to have a magnitude 3. It appears to be fading now, as later observations by Mr. W. M. Lindley, Mr. F. M. Holborn and Dr. W. H. Steavenson give its magnitude as about 3.5. It has also been observed at Yerkes ; the velocity of expansion has been estimated to be 4,000 km. per second.
